Despite sweeping the first three stages and leading 283 of 400 laps, William Byron failed to finish the job in Sunday night’s Coca-Cola 600 at Charlotte Motor Speedway. And for that, you can blame Ross Chastain.
Starting last in a backup car, Chastain methodically moved his way forward and grabbed the lead for the first time when he seized it from Byron on Lap 348 of 400.
